Electrochemical devices that either generate electrical energy via chemical reactions or trigger reactions with electricity have been explored for a variety of applications. Among them, sensors and energy storage devices attract tremendous research interest in recent years, mainly due to the rapidly expanding market of wearable and portable devices for applications in clinical diagnosis, physiological monitoring, environmental detection and robotics. To realize performance enhancement of varies electrochemical devices, including sensor stability and energy storage capacity, novel and unique hierarchical nanostructures were designed and synthesized. Nanostructured electrochemical sensors demonstrated effective enzymes immobilization and enhanced devices robustness, which is highly desirable towards stable and reliable noninvasive health monitoring. Meanwhile, scalable and printable approach was developed to integrate high performance electrochemical devices into monolithically integrated self-powered systems. The as-developed nanostructured electrochemical devices in conjunction with printable approach show great potency in fabrication of various wearable integrated self-powered devices for personalized healthcare monitoring applications.
